Today's Independent has a pretty decent article on beer, in parts heavily quoting Adrian Tierney-Jones and also Alex Bell, head brewer of O'Hanlons
It's certainly better than most articles on beer in the British press, including the quality papers. It's such a shame than that the writer was allowed some freedom to make up their own stuff and not rely totally on those better qualified to write such pieces.
If you can't be bothered to read the whole article, just scan to the bottom paragraph, and read these fascinating words:
"What determines whether a beer is an ale, a bitter or a larger is down to the amount and type of hops as well as the malted barley, but is primarily due to the strain of yeast." And yes, I've reproduced the wonderous spelling mistake. I'll say no more.
